CEUS System Networking

    "lets talk to CEUS"

    The CEUS computerized reproducing piano system was developed for two purposes:

      1. to record performances on the piano, and
      2. have the piano replay the performance with the highest possible fidelity.

    The CEUS is a personal computer system that provides comm ports so that the system can communicate with other devices through either the 8 pin RJ-45 LAN (Local Area Network) Ethernet port, or by a USB port, or by the MIDI (a lower resolution standard) in and out ports. The CEUS system is easy to use without the PC but at the same time CEUS is completely PC compatible.

    Right: CEUS connected to my Apple MacBook Pro notebook computer by means of an optional Cross Over cable.

    The CEUS is also fully MIDI (Musical Instrument Digital Interface) qualified, this is a protocol that enables electronic musical instruments such as the CEUS, other keyboard controllers, computers, and other electronic equipment to communicate, control, and synchronize data with each other. MIDI does not transmit any conventional recorded video or audio media, instead MIDI transmits "event messages" such as the pitch and intensity of musical notes to play, control signals for parameters including volume, vibrato and panning, cues, and clock signals to set the tempo. So it is possible to record in MIDI format then edit these files with an editing software (such as Steinberg's Cubase or Nuendo). If you have the completed edited MIDI songs, then you can convert them very easy into .boe and let the CEUS play.

    The CEUS User's Guide is provided with the system and is also available on line from the L. Bösendorfer Klavierfabrik web site. This color illustrated fifty-three page operating guide is full of information and advice that is well detailed about the CEUS. But with my only simple knowledge of networking, I found myself wanting to write down the steps involved to communicate with CEUS. Furthermore, I wanted to see exactly what one might expect to see when bringing up the CEUS piano on a network. So I wrote this article to share my experiences and let others know it really is a simple matter to talk to CEUS.

    BOEdit - .BOE File Editing Software:

    In early 2011 Bösendorfer Klavierfabrik will release BOEdit, software written specifically to allow the editing of CEUS recording .boe files. The software features two workspaces, a track editor and a note editor. This will permit the shifting of individual notes within the data file of a recorded performance in 2-millisecond resolution increments, edit the length and volume of notes, optimize the velocity of the notes. Edit the slightest movements of the piano keys and pedals too. In the track editor and entire performance may be edited; cutting and pasting portions, or editing out mistakes. Throughout these processes numerous 'undo' possibilities are possible too, though it is simple enough to periodically save complete working versions of each file too. Best of all, BOEdit is easy to learn and use, even for those people who have no prior music editing experience. I will add more information to BosendorferImperial.com about this development as the first release version of BOEdit becomes available.

    It is possible that in time the .boe file standard may be even more widely adopted, so that some of the more capable third party music editing and recording software too will be able to read and work with the .boe data. In time third-party software too may even permit other functions including the synthesized playback of .boe files on a PC.
